Answer:
2x^2 + 3x + - 2 + 7
4x + 3x - 2 + 7
7x + 5
Step-by-step explanation:
2x^2 + 3x + - 2 + 7
4x + 3x - 2 + 7
7x + 5
No x=5 since 5 is the input. The input is always equal to x and the output is always equal to y. So x=5 and y=x+5
Answer:
y = 2x - 6
Step-by-step explanation:
Use the slope-intercept form of the equation of a line.
y = mx + b
y = 2x + b
4 = 2(5) + b
4 = 10 + b
b = -6
y = 2x - 6
